is :i partial view similar to Fig'. 5, iown on an enlarged scale; and f Fie', 8 is a view similar to Fig. 5, showing a nu i'icd rtorni o'i the earth receiving and elevating; wheel.

Reioiringi' to the drawings, a machine .is shown comi'irising' a vehicle having,` a body i() having' a bull wheel, a small wheel at the opposite side thereof and a second small wheel disposed inwardly of the bull wheel :pid rearwardly of the axis thereof. rIlle bottom portion of the body lt) is equipped with hinged doors l()uv adapted to swing downward as shown in dotted lines in Fig. 2, so that the material can be dumped from said body. 'lhe doors l0 have chains ll. connected thereto, which chains extend upwardly and forwari'liy to a shaft ,l2 to which they are connected, which sha't't is journaled in bearings 13 at the sides of the. body l0. The shaft l() has secured thereto a ratchet whec` let and a hand lever pawl l is intermediately pivoted to a bracket t6 secured to the side of the body 10 and adapted to engage the i teeth of the ratchet wheel 14 to prevent rotation of said wheel in a direction to let the doors l0 drop. The pewl 15 is urged to position to engage wheel. t4; by a small tension spring 17. A lever 1S is journaled on shaft l2 at one side of ratchet wheel lil., which lever is bent into substantially right-angled shape and has pivoted thereon a pawl. 19 adapted to engage the teeth of wheel 14. The pawl 19 is connected by a link 2() to an operating grip handle x21 piyoted to the handle end of lever 18 whereby said pawl l9 may be disengaged from the wheel lil. The body l0 has bearings 1t" intermediate its ends, in which is journa-led an axle Q2 having secured to its ends the operatin wheels 23 for the body 10. The body 10 has secured thereto at its forward end converging bars at secured to a central member 25 and a top bar 26 is also secured to the front end of the body 10 and to the member The bar Qrt and a lower bar 27 projectbeyond the end of iernber to form a clevis which constitutes the draft means for the body l0, bywhich it may be connected to a tractor or other traction means. The body l() has bearing brackets Q8 secured at each side thereof and au axle member 29 is disposed in said bearings and adapted to oscillate therein. The axle 29 isI formed at one outer end shown at the right hand side oli Fig. 2 with a crank portion on which port-ion is revolubly mounted a hub 30 of an earth receiving and elevating wheel 30. The wheel 30 includes, among other parts, a circular rim 30" and secured to this rim adjacent the outer edge thereof to project to 'ard the hub 30. is a circular channel member 30C. 'lhe wheel has outer and inner spokes 30" and 3 Q respectively, the outer spokes heilig bent substantially at right angles at their outer ends to be riveted to Vthe inner flange of the channel member 302 and being bolted at their inner ends to a tiange extended from the hub 30% The inner spokes 30e are angularly bent at their outer ends and are secured to the outer ends of the outer spokes 30 and extend diagonally therefrom to be secured at their central ends to an inner circular flange extending from hub 30a. The rim 30b has secured thereto on its outer side a plurality of cleat members 30f.` A plurality of pins 7 7 riveted or otherwise secured to the outer side of the inner flange of channel member 30C project through the web ofthe channel member and extend in wardljiyv therefrom. Plates 78 have hubs 78L adjacent one end which are journafled on the pins 77 and held thereon by cotter pins 79. The plates 78 are of generalarcuatecurvature in the same curvature as the inner flange of the channel member 30, and the plates have projections 7 8b at their 'inner ends offset somewhat from the axes of the pins 77. The plates are so spaced that the outer edges of the plates will engage with the projections 78b of adjacent plates when the plates swing inwa rdly, as shown in dotted lines Fig. 7. The channel. member 30C has rows of holes 30g in the web thereof arranged concentrically relative to the various pins 77, and bolts 8O are adapted to be secured in any of these holes to limit the outward swinging movement of the plate 78. lith this construction, it will be seen that the rim 30", channel member 39C. and plates 78 form a channel in the wheel divided at points into a series of compartments by the plates 78. At least one of the wheels 23 formed as a disk wheel and the disk of this wheel as shown at the right hand side of Fig. 2 is disposed closely adjacent the wheel 30 so that said disk of Wheel 23 partly closes the said channel. A plate 3l is disposed at the inner side of the wheel 30 and as shown in Fig. 1. said plate is circular in outline, and substantially flush with the inner side of the rim 30b and has its lower odge closely approaching the periphery of the wheel Q3. said inner edge extending from the wheel 23 diagonally upwardly and then extending vertically. The plate 31 is supported and braced from the body l() by 1ne1nber 31a. A plate 49 is provided, disposed at the. top of the wheel 30 and adapted to have one end project into the channel formed vin said wheel. Said plate is bent as shown in Fig. 3 and has another plate 49 bolted thereto having spaced bosses or hubs 49h. Supporting rods 5l extend into the bosses 49 and are secured therein by suitable pins or set screws 52h. rl`he rods 51 extend through bosses 52 formed on a plate 52 which is secured to the side of the body l0. A chute or guide plat e is disposed beneath the plate t9 substantially flush with the plates 78 at the top of the wheel 30 and another chute or guide plate 50" is disposed some distance. below the plate 50 and the end of an endless conveyor' to be later described, and extends downwardly and inwardly to the top of the body l0. The axle Q9 has a gear segment 32 oscilla-tably mounted thereon adjacent one of the bearings 28 which is engaged by a worm gear 33 secured to shaft 34 journaled in bearings 35 secured to the side of body 10 and projecting forwardly to the front of said body, said shaft being equipped with a hand wheel 36 at its front end. The shaft 34 is El u i Cotter pins 37C.

kept from endivise movement by collars 34a secured thereto at each side of one of the bearings 35. .A pair of arms and 321' project` forwardly from the member 32, each having; a plurality of holes therethrough and the upper ends of rods 37 are formed as hooks adapted to project through any one of said holes. .The rods 37 at their lower ends eX- tend into socket members 38. said rods having4 their lower terminals bent at right angles lo project laterally into slots 88a formed in tt e sides of the ineinl 88, said members 38 b y.ng pivotally connected at their loiver ends respectively to a pair of bars or levers 3S).

@oiled compression springs 37a surround the yrods 37 having' their lower ends engaging the tops of the members 38 and having` their upper ends engaged by collars 37b disposed on rods 37 and-held in position thereon by The levers 39 converge at their forward ends and are received in a channel men'iber Ll() Which is connected to the side of the body l() by a headed and nntted holt ll passing therethrough and through the lever B9 so that r"iid levers are )ivoted on said bolt. The levers 239 are bent downward substantially at right angles at their rear ends and secured to the rfi' side of the scraping ineinb'ir or blade fl-L/l which ci;- tends at an angle to the longitudinal axis of the machine as shoivn in Fig'. 3, having its inner end forwardly. The axle 29 projects at one sideof the bodyT l() and bearing 28 and has secured thereto a segment e3 en- Ig'ed by a Worm ai' le carried on the shaft which shaft journaled bearings Ll5 secured to one side of the body l0 and proat the forward end of said body, Where it has a hand wheel e7 secured thereto. Said shaft prevented from endivise movement by collars d8 secured at each side of one of the bearings el@ as shown in Fig'. 3. Ey turning' hand vrhecl d'7 the axle 29 is turned and thecrank portion thereof will raise and lower the wheel BO.

An endless conveyor is provided, extending' transii'ersely of the body l0 and comprises a frame havinej the lono'itudi illy eX- -i'ending members 53 at each side tl'iereof haying journaled therein shafts and havsecured thereto rollers 56 Aover which u a conveyor belt 57. lt Will be seen that 'he members extend above the top run of belt (i. forming` a trough. A shaft 58 extends transversely of the members 53 intermediate their ends and is disposed substantially above one of the sides of the body l() being' journaled bearings secured to said sides, the members 53 having' portions journaledon said shaft. A sprocket 60 is secured to shaft 58 and a chain 6i runs over this sprocket also over a sprocket G2 secured to the shaft 55. A Worin Wheel gear G3 is also secured to shaft 58 and meshes with the Worin gear secured to a shaft'j journaled in the spaced bearings of a forked bracket 66 secured to the bodv l0. the Worm gear (Sel being disposed bet-Ween the spaced bearings of said bracket. The shaft has a sprocket Wheel 67 secured at its outer end thereto and la chain 68 runs over a sprocket 6i' and over a large-r sprocket ($9 journaled n axle and disposed .at one side of one of the ivheels Q3. The sprocket (59 adapted to be clutched to the axle to be driven thereby, and for this purpose formed at one end as a halfclutch adapted to engage With a slidable halfclutch 'member 70 splined to the axle S22, member 70 having;l a `groove therein engaged by the lower forked end of the shiftl lever 7l pivoted in the bracket- 72 secured to the side of the body l0, the upper end of the lever 7l beine' formed as a handle and extending` above bracket 72. The sprockets 69 can thus be connected to the axle so as to be driven thereby when desired. The endless carrier coi'nprising the members 53 is oscillatable about the shaft 5S and said carrier is adapteiil lo he held in various positions b v a swinging a'i'in '(5-3 pivoted'at one side of the body lO and ha ving;l therein a plurality of holes 73, a headed and nutted bolt 7d beingadapted to pass through one of the menibers 53 and through any one'of the holes 7 3a.

ln operation, when the device is used for excavating' and elevating` earth or dirt, the

lade l2 will be brought to the proper position to scrape or excavate a layer of the desired thickness. This blade is adjusted in position by manipulation of the hand Wheel 36 which oscillat-e's the gear segment 82 and moves the 'levers 32'. The end Wheel 47 is thus manipulated to oscillate the crank shaft 29 by means of the Worm gear 44 and gear segment The wheel 30 is lowered so that its rim is substantially in contact with the ground. but slightly spaced from the surface thereof and so the cleats BO will enter the ground` and obtain strong traction effect thereon. lf the elevated dirt is to be discharged into the. vehicle body l0, the carrier comprising' members 52 Will be raised to the position shown in dotted lines in Fig. 2. Vl`he doors 10' in the bottom of the body lO will7 of course, be closed and it will be noted that said doors can be moved to closed position bv oscillating lever 18 so that paivl 19 successively engages they teeth of the ratchet u'heel le and rotates shaft l2, thus Winding up the chains ll. rlhese chains, as shown in Fig'. l, pass over the crank shaft 29. The doors will be held in closed position and wheel ld kept from reverse rotation by the pau'll. The plates 78 below the center of the wheel 30 will be held by gravity in downwardly swungy position across the channel in the Wheel as best shown in Figs. 5. 6 and 7, so 'that'the lower portion of the channel of the wheel Will be divided into compartments.

l llt llG The plates 78 above the center of the wheel will be held by gravity swung toward the center of the wheel so that adjacent plates 78Y will contact each other to form a substantially closed arcuate partition in the wheel in centrally disposed relation from the upper half of the rim 30". The machine will be drawn along the giound by some traction means connected to the bars 2G and 27. The blade 42 will scrape up dirt which will be moved rearwardly and outwardly along said blade and the dirt will be raised somewhat and moved into the compartments formedl by the plates 78 in the channel of the wheel. The earth moved into the wheel 30 will be carried by the rotation of the wheel upwardly, whereupon as the wheel progresses various upwardly moving plates, shortly after passing points about level with the center f the wheel, will drop to their inward positions to clear the plates from theupper portion of the wheel. It will be seen, as indicated by the arrows in Fig. 1, that the side of the wheel 23 which is closely adjacent the wheel 3() rotates in the same direction as wheel 30. The said wheel 23 will thus engage the earth in wheel 30 and will co-operate with said wheel and the blades 78 in the elevating operation and assist in the elevating of the earth. It will be understood that wheel 30 will be moved by the Contact with the ground of the cleats 30t therein, so that the lineal speed of the centers of said wheels 23 and 30 is the same. The earth in the wheel 30 would naturally tend to assume a certain angle of repose, but owing to the fact that the dirt is constantly moved into the wheel by the blade 42 and urged along with the wheel by the wheels 23, the dirt becomes packed in wheel 3() between the plates 78 and this causes the dirt to be moved upwardly in a more or less compact mass until the plates swing to their central positions whereupon the dirt in the lower part of the channel will force the dirt in the upper part thereof upwardly. After the dirt moves past the wheel 23, it comes opposite the plate 2:31 and is thus confined in the channel in wheel 30 until it reaches the top of said wheel. The dirt then is engaged by the scraper blade 49 which extends into the channel in wheel 30 and the dirt is moved out of the wheel by blade 49, so that it falls from the inside of channel and is guided by the plates C and 50a into the body 10 of the ve hicle. It will be seen that the plates 78 will Vnot interfere with the action of blade 49. This operation is continued until the desired amount of dirt has been collected in the vehicle. If it is desired then to transport the dirt to some other place for dumping, the hand wheel 47 will then again be manipulated to turn crank shaft 39 and elevate wheel 30, so that it is out of contact with the ground. 'Ihe vehicle is then transported to the desired place and the dirt dumped from body l0 by opening af the doors a. It will be noted that as the vehicle is drawn along the ground in operation, the blade 42 is held down yielding- 1y in proper position by the springs 37a. This is desirable so the blade may raise and pass over any obstruction such as a hard rock in the ground.

It it is desired to load the dirt elevated into another vehicle, the endless conveyor including members 53 will be moved to the position shown in f'ull lines in Fig. 2. It will be seen that the blade 49 clears the endless carrier so that the latter can be moved as clearly shown in Fig. 3. lVhen the endless carrier is in the position shown in full lines in F ig. 2, the dirt or earth from wheel will be moved by the scraper blade 49 and will be dischargedfrom the plate 5() onto the endless carrier and moved thereby to one side of' the vehicle. The endless carrier will be driven through chain 68, sprocket 69 being connected to axle 22 as already described.

The amount of dirt that is elevated by the wheel 39 may be varied by placing the bolts 80 in various openings 30g in the channel member 30C. The bolts S0 act to limit the distance that the plates 78 will be carried across the channel in the wheel as the lower portions of the plates fall by gravity downwardly during rotation of the wheel, and, accordingly, the position of the plates 78 as deterniined by the stop bolts 8O will largely determine the amount of dirt that will be carried into the channel of the wheel by means of the excavating tool 42.

In Fig. 8, another form of elevating wheel is shown. This wheel which is designated generally as 75, includes a hub portion a rim 75", a centrally projecting flange 75C adjacent the outer edge of the wheel, a circular fiange 75d concentric with the rim and extending rom the flange 75c to the inner edge ot' the wheel, and outer and inner spokes 75c extending respectively from the flange 75c and 75 to spaced flanges on the hub 75. On the central side of the rim 7 5), there are secured angular lugs 75f, while on the outside of the rim there are secured cleats 7 6 corresponding to the cleat members 80f. It will be seen that the wheel illustrated in Fig. S is very similar in all respects to the wheel 30 with the exception that the flange 75d and lugs 75f are substituted for the plates 78 and pins 77. The wheel 75 will be mountV ed on the crank shaft 29 and disposed adjacent one ofthe wheels 23 and plate 3l in the same manner that the wheel 30 is mounted and disposed.

Then the wheel 75 is used, the blade 42 will move the dirt into the channel formed by the rim 75", flange 75c and flange 75d. As the wheel 75 rotates, the dirt will be carried upwardly by the wheel and discharged therefrom by the blade 49. The lugs 7 5t will assist in the raising action as will the closed side of the adjacent moving load bearing wheel Q3 and the packing of the dirt in the channel of the wheel. `While in the embodiment of the invention illustrated, the elevating wheel and carrier are shown mounted on a vehicle of the cart type, one wheel of which is used to operate the carrier or conveyor, it will be understood that with slight modifications the elevating wheel and carrier could also be readily attached to and used with a great variety of similar vehicles such as various trucks, dump wagons, tractors and the lil; rlhis adaptability is largely due to the mounting of the elevating wheel and the ease with which this elevating wheel and mechanism can be thrown into operative and inoperative positions. (bviously, such adaptations as above mentioned are within the scope of this invention.

, Further, while in the embodiment of the invention illustrated a scraping blade is used for excavating or scraping the material into the elevating wheel, the invention contemplates the use of any of the many well known excavating or material handling devices for this purpose such as disk or mold board plows and scraping blades set at various angles. blades could be used and the material scraped from the outer side of the wheel into position to enter the wheel and that material could be moved or loaded into the elevating wheel by sweeping brooms.

It is also obvious that while in the embodiment of the invention illustrated, the endless carrier extends transversely of the vehicle, the said carrier could extend in other directtions and could, if desired, be made to extend parallel with the elevatingwheel and deliver the material forwardly or rearwardly of the line of travel, such arrangements being within the purview of this invention.

From the above description it is seen that applicant has provided a novel and eiiicient dirt excavating and elevating apparatus and one in which the dirt is simultaneously loaded for transportation either in the body of the vehicle forming part of the machine or in another vehicle moving alongside thereof. The excavating, loading and transporting of the earth is therefore carried on as one simultaneous operation and the separate loading operation is eliminated. llhe parts of the machine are comparatively few and the same are easily made and assembled. The machine is quite rugged in construction and able to withstand the rugged use to which the machine is put.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which, generally stated, consists in a device capable of carrying out the ,ob-jects above set forth, in the novel parts lt is obvious that several scrapingv and combinations of parts disclosed and delined in the appended clain W'hat is claimed is zl. ln a machine ofthe class described, a vehicle having a body and adapted to be drawn along the ground, n adjustable excavating tool carried by said vehicle, a pairof sr sporting wheels for said ve iicle, and an earth receiving and elevating wheel closely adjacent the outer si le of one of said supporting wheels disposed to receive earth moved by said tool one of said supporting wheels having flat side forming closure for said elevating wheel.
